16956-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16956-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16956-44:
(7*1)+(6*6)+(5*9)+(4*5)+(3*6)+(2*4)+(1*4)=138
138 % 10 = 8
So 16956-44-8 is a valid CAS Registry Number.

Convenient One-Pot Two-Step Synthesis of Symmetrical and Unsymmetrical Diacyl Ureas, Acyl Urea/Carbamate/Thiocarbamate Derivatives, and Related Compounds

Hernandez, Anolan Garcia,Grooms, Gregory M.,El-Alfy, Abir T.,Stec, Jozef

, p. 2163 - 2176 (2017/05/05)

A wide range of chemicals such as amides, hydrazides, amines, alcohols, carbazate, and sulfonate were reacted with acyl isocyanates generated by the reaction of primary amides with oxalyl chloride to give symmetrical and unsymmetrical diacyl urea derivatives, acyl ureas/carbamates/thiocarbamates, and related compounds. This method provides means for convenient one-pot, two-step synthesis of compounds bearing urea, carbamate, and other functional groups from cheap and commercially available starting reagents. It is expected that the results presented in this report will expand the medicinal chemist’s toolbox.
